Allow adb forward to traced consumer socket
Currently shell can connect to the traced_consumer_socket allowing it to
configure/start/stop and collect traces. This allows a host tool (e.g. Android Studio or
https://ui.perfetto.dev) to connect to the device via adb and collect traces. It would
be better if rather than executing shell commands the host tool could directly communicate
with the consumer socket. This is possible using adb forward:
adb forward tcp:9903 localfilesystem:/dev/socket/traced_consumer
However in this case adbd is connecting to the socket - not shell.
This CL allows adbd to connect to the socket which allows host tools to collect
traces without having to do everything though shell commands.
